    摘要： A tieback connector for attaching a riser to a subsea production assembly is provided. The tieback connector includes a main body adapted to be coupled to the subsea production assembly having a central passageway sufficiently large to pass an end of the riser string therein and a connector positioner coupled to the main body, which is adapted to secure the tieback connector around a circumferential surface of a wellhead of the subsea production assembly. The tieback connector further comprises an aligning extension portion defined by a funnel-shaped tip, which aids alignment of the riser terminus during landing of the riser string onto the wellhead. The tieback connector secures the riser to the wellhead.

    摘要： A system for supplying pigs to a subsea pig launcher using a system carried and controlled by a remotely operated vehicle. The pigs are carried in racks that hold multiple pigs. The racks are extended and the pigs are allowed to drop into the barrel of the subsea pig launcher. The system is also equipped with a system that retracts the racks if hydraulic and electrical power is lost during the reloading process so that the remotely operated vehicle can be retrieved to the surface safely. The reloading process can be carried out by a remotely operated vehicle support vessel without the need for heavy lifting equipment or a large deck area.
